SSW EVENT COULD DIVERT ‘THE POLAR EXPRESS’ TO EUROPE AND NORTH AMERICA THIS HOLIDAY SEASON

by Cap Allon, November 16, 2019 in Electroverse


The GFS and it’s ensembles are forecasting a dramatic reduction in westerly Zonal winds over the North Pole during the latter half of November and throughout December.

Conversely, October and the first half of November brought very strong Zonal winds at 60N, which went hand-in-hand with below-average temperatures at the Pole — Zonal winds in the stratosphere strengthen as the temperature over the North Pole drops:

IMPACTS OF AN SSW

Following the onset of an SSW event, temperatures at the pole will often climb sharply, and the high altitude winds will have reversed to flow in an eastward direction instead of their usual westward one.

These eastward winds progress down through the atmosphere and weaken the jet stream, often resulting in easterly winds near the surface which usually bring with them a dramatic drop in temperatures across Europe and North America.

Media Ignore Vast Summer Cold Across Northern Hemisphere; Southern USA, Russia See “Record Lows” In July

by P. Gosselin, August 3, 2019 in NoTricksZone


While the headlines naturally focused on an intense heat wave over a region centered over France and Germany last week, the global warming ambulance chasers worked overtime avoiding and ignoring the real story: vast, continent-wide cold spreading across Russia.

Heat and cold zero-sum

First at the European Institute for Climate and Energy (EIKE), Klaus Öllerer reported how the Sahara heat ended up being a “zero-sum” event for the northern hemisphere region of Europe and Asia.

Öllerer wrote last week that despite the heat that took place in large parts of Europe, it was cooler than usual in other neighboring parts. Only a certain area in Central Europe (purple area) was particularly hot. Around it, it was less warm (yellow) and cooler than usual (blue):

“Even large parts of the Sahara are cooler than usual (blue). This is no wonder, as the heat is now in Europe and cooler air flows into the Sahara,” Öllerer wrote.

“The above-average warm areas balance out with the above-average cold areas,” he concluded. “The current warming is a zero-sum game! Historically, such events have occurred again and again.”

“It is even the case that in cooler times – such as the Little Ice Age – warm summer extremes were more frequent than in the last one hundred years and more,” Öllerer added.

Northern Europe July Temperature Sees NO WARMING Over Past Decades. Global July Not A Record High!

by P. Gosselin, August 20, 2019 in NoTricksZone


Parts of Europe have seen a couple of brief but intense heat waves this summer, and so some of the public got brainwashed by the media into thinking the continent’s summer climate is rapidly getting hotter and that all this is the new normal.

Yet, when we examine the unaltered data from the Japan Meteorology Agency (JMA) for locations in northern Europe that have long-term datasets available, we see there has been no July warming trend over the past decades. Media reports suggesting otherwise are nonsense.

Ireland

Looking at 6 stations in Ireland, we have the following for July:

 

Data source: JMA.

Overall, Ireland’s mean July temperatures have been cooling off modestly over the past 3 decades and more, even though three stations are located at airports.

Snow Cover, Ice Volume Growth Show Global Climate Is A Lot More Than Just “Surface Temperature”

by P.  Gosselin, March 30, 2018 in NoTricksZone


Although a number of scientists are hollering that 2017 was “among the warmest on record”, we are not seeing any manifestation of this, at least over the northern hemisphere, where ironically snow and ice have shown surprising extents. This year the northern hemisphere winter has been surprisingly cold and brutal over a number of regions.

On March 20, 2018, northern hemisphere snow and ice cover was over 1 standard deviation above normal. Source: Environment Canada.

 

An “Exceptionally large amount of winter snow in Northern Hemisphere this year

by A. Watts, March 14, 2018 in WUWT


From the Snowfalls are now just a thing of the past department and the Finnish Meteorological Institute comes this press release today.

Exceptionally large amount of winter snow in Northern Hemisphere this year

The new Arctic Now product developed by the Finnish Meteorological Institute shows with one picture the extent of the area in the Northern Hemisphere currently covered by ice and snow. This kind of information, which shows the accurate state of the Arctic, becomes increasingly important due to climate change. The Arctic region will be discussed at the Arctic Meteorological Week which begins in Levi next week.

The Long Winter Of 2017/18…Numerous Records Set As Ferocious Cold And Snow Batter Northern Hemisphere

by P. Gosselin, February 20, 2018 in NoTricksZone


The long term forecast for Europe, where it is already colder than normal, shows temperatures plummeting to near -20°C in parts of Central Europe by early next week, extending what has been already a brutal winter.

Europeans longing for spring will just have to be patient for awhile. Indeed this winter has been a harsh one across the northern hemisphere with record cold temperatures being set from Siberia to North America to Japan. Also a number of places have seen record snowfalls.

The European Alps have had one of the snowiest winters in years as snow continues to pile up meters high.

Long list of harsh winter events (…)

Again And Again: Experts And New Findings Show No Link Between European Storm Activity And CO2

(German text translated/edited by P. Gosselin)

This month two major North Sea storms have hit Europe rather severely, and not surprisingly the usual climate ambulance chasers were out in force to try to pin the blame on man’s activity, and in doing so ignored the climate history that provides us with the proper perspective. We look at some analyses of past German storm activity.

COLLAPSE OF THE EUROPEAN ICE SHEET CAUSED CHAOS

by Maja Sojtaric, June 27, 2017


The Eurasian ice sheet was an enormous conveyor of ice that covered most of northern Europe some 23,000 years ago. Its extent was such that one could have skied 4,500 km continuously across it – from the far southwestern isles in Britain to Franz Josef Land in the Siberian Arctic. Suffice to say its existence had a massive and extremely hostile impact on Europe at the time.

This ice sheet alone lowered global sea-level by over 20 meters. As it melted and collapsed, it caused severe flooding across the continent, led to dramatic sea-level rise, and diverted mega-rivers that raged on the continent. A new model, investigating the retreat of this ice sheet and its many impacts has just been published in Quaternary Science Reviews.

Lowest Solar Activity In 200 Years Accompanied By High Northern Hemispheric Snow And Ice

by P. Gosselin from F. Bosse and F. Vahrenholt, June 18, 2017


In May the sun was very quiet as sunspot number was a mere 18.8, which is only 36% of what is typical for the month this far into the cycle. Seven days saw no sunspot activity at all.

The following chart shows the current cycle, Solar Cycle 24 (red), compared to the mean of the previous cycles (blue) and the similarly behaving SC 5 (black).

It’s clear that the current cycle is significantly weaker than the mean and far weaker than the cycles we saw throughout most of the warming 20th century.

New Paper: Northern Hemisphere Temperatures Rose 4–5°C Within ‘A Few Decades’ 14,700 Years Ago

By Kenneth Richard , April 2017


According to a new paper, the Bølling Warming event 14,700 years ago raised the surface temperature for the entire Northern Hemisphere by 4 to 5°C within a few decades.  This is a hemispheric warming rate of approximately 2.0°C per decade, which is 40 times faster than the 0.05 °C per decade global warming rate since 1850 (and 1998).

Atlantique Nord : le risque d’un refroidissement rapide au XXIe siècle revu à la hausse

par D. Swingedouw et al., CNRS, 15 février 2017


Dans le cadre du projet européen EMBRACE, une équipe d’océanographes a réexaminé ces 40 projections climatiques en se focalisant sur un point névralgique au nord-ouest de l’Atlantique Nord : la mer du Labrador. Cette mer est le siège d’un phénomène de convection, qui nourrit à plus grande échelle la circulation océanique de retournement. Ses eaux de surface se refroidissent fortement en hiver, deviennent plus denses que les eaux de profondeur et plongent vers le fond. La chaleur des eaux profondes est transférée vers la surface et empêche la formation de banquise
